Orthodontic camouflage versus orthodontic-orthognathic surgical treatment in class II malocclusion: a systematic review and meta-analysis

Abstract

Abstract. This systematic review was performed to compare dental, skeletal, and aesthetic outcomes between orthodontic camouflage and surgical-orthodontic treatment, in patients with a skeletal class II malocclusion and a retrognathic mandible who have already finished their growth period. A literature search was conducted, and a modified Downs and Black checklist was used to assess methodological quality. The meta-analysis was conducted using the DerSimonianLaird random-effects method to obtain summary estimates of the standardized mean differences and corresponding 95% confidence intervals. Nine articles were included in the qualitative synthesis and seven in the meta-analysis. The difference between treatments was not statistically significant regarding SNA angle, linear measurement of the lower lip to Ricketts' aesthetic line, convexity of the skeletal profile, or the soft tissue profile excluding the nose. In contrast, surgical-orthodontic treatment was more effective with regard to ANB, SNB, and ML/NSL angles and the soft tissue profile including the nose. Different treatment effects on overjet and overbite were found according to the severity of the initial values. These results should be interpreted with caution, due to the limited number of studies included and because they were non-randomized clinical trials. Further studies with larger sample sizes and similar pre-treatment conditions are needed.

The Effect of High-Frequency Vibration on Tooth Movement and Alveolar Bone in Non-Growing Skeletal Class II High Angle Orthodontic Patients: Case Series

“…The increased demand of non-surgical techniques to correct skeletal mal-relationship cases especially in non-growing or slow growing patients is increasing [25,26]. In this study, it has been shown that the use of HFV enhances treatment outcomes in challenging high-angle orthodontic cases when normally, surgical options would have been suggested to manage these cases.…”

“…It is of particular importance to note that adult or non-growing patients would need relatively longer treatment time than growing individuals [27]. In particular, camouflage treatment or non-surgical treatment in skeletal mal-relationship cases [25] would be needed. The relatively faster treatment in the presented cases in this report could be due to the reported scientific evidence that HFV enhances bone resorption during orthodontic treatment as well as bone deposition.…”

Nonsurgical Orthodontic Intervention of a Severe Class II Case Accompanied by Posterior Crossbite Using a Miniscrew-Assisted Straight Wire Technique

“…With the recent advancement in anchorage devices and the introduction of miniscrews in orthodontics, orthognathic-like results can be achieved by utilizing such devices [6]. In patients with Class II malocclusion, it was shown that a maxillary incisors retraction of 8.2-9.3 mm can be achieved by using miniscrews [7, 8].…”

Effects of different nose types on class II treatments for female patients

“…Out of all the available treatments for these patients, the first option is usually skeletal structure intervention in conjunction with orthodontics and surgery, which is referred to as orthognathic surgery. The other option involves masking the underlying skeletal problem by moving the maxillary dentoalveolar structures and correcting occlusion, which is a method called camouflage treatment [1].…”
